Re: [sumo-user] Error in FCD output using device

[Jakob Erdmann <namdre.sumo@xxxxxxxxx>]

For me, the .gz output is working as expected. In your case it might be related to parallelization or even output data size (iirc you are writing multi-gigabyte output files).Can you narrow down the circumstances leading to the crash?

regards,

Jakob

Hello,

to restrict fcd output by type, enable the device by default and then switch it on in the vType definition:

--fcd.device.probability 0

    <vType id="passenger4" ...>
        <param key="has.fcd.device" value="true"/>
    </vType>

Hi Jakob,

 

I would like to restrict the FCD output to specific vehicle types.

 

Using the vehicle id it is working fine:

  --device.fcd.explicit actuated_06_0,actuated_06_1

 

Leads to:

   <timestep time="21611.00">

        <vehicle id="actuated_06_0" x="6.807090" y="50.926368" z="70.000000" angle="71.848000" type="passenger1" speed="13.476307" pos="0.000000" edge="-24815294#0" slope="0.000000"/>

        <vehicle id="actuated_06_1" x="6.811326" y="50.906366" z="77.000000" angle="296.588662" type="passenger4" speed="11.113631" pos="0.000000" edge="-263269156" slope="1.439594"/>

    </timestep>

 

Using the type (e.g. “passenger4”)

  --device.fcd.explicit passenger4

 

The fcd output ignores all vehicles and just writes the timestep.

 

<timestep time="21611.00">

 

Can you confirm that the used “type” is correct as stated in the docu (https://sumo.dlr.de/docs/Simulation/Output/FCDOutput.html) ?

Can you fix it please?

 

Further I tried the “.gz” compression of the fcd output. At the end of the simulation the files remains empty and the simulation failed with segmentation fault.

 

Best

Florian
